articles from being wrapped or twisted about rolls or rollers. It is particularly intended for use in connection with the backing roll of p a rotary brush washing machine to prevent clothing or other articles being washed from becoming wrapped around the backing roll.

Generally speaking, it comprises a stripper blade provided with a beveled edge which is resiliently pressed against the perimeter of the roll and which is so mounted as to prevent its sagging or bending'out of contact with said roll intermediate of its length.

Novel features of construction and arrangement of parts will appear from the following description.

In the accompanying drawings, Figure l is a broken end view of a washing machine fitted with my invention; Fig. 2 is a broken plan view of the same; Fig. 3 is an enlarged view showing @the relation of the stripper blade to the backing roll; the stripper links being omitted for the sake of clearness; Fig. 4 is a broken front elevation showing one end of the stripper blade dismounted; Fig. 5. is an edge view of one of the links by. means.

of which the backing roll is supported from view of the same; Fig. 7 is an inner face view of one of the stripper links; Fig. 8 is a side view of oneof the stripper pins; Fig. 9

is a side elevation of one ofthe' halves of.

one of the two part bearing blocks of the backing roll, and Fig. 10 is a front View of said bearing block.

The following is a detailed description of the invention. I i

A represents one of theendplates of a rotary washing machine, the two ends thereof being similar and having journaled beto the same forms no part of the-present invention, it isnot shown.

C is the backing roll held resiliently in contact with 'the brush B and supported in the following manner: The ends of the roll C are each provided with an axial projection, preferably the ball projection 2, which is journaled in the two part socket bearing block 3 which is seatedinthe annular bearing box at formed on the inner face of the suspension link 5, whose upper end is pivoted to the end plate A, as at 6. The outer portion of the annular box 4 is reduced as at 7 in external diameter for a purpose to be described- The backing roll C, swi-ngingly supported at both ends, as above described, is held resiliently against the brush B in the following manner, at either side. 8 is a rod whose outer end is pivotally attached to the lower. end of the suspension link 5 and whose sion of the springs at either end of the machine may be regulated by means of the nuts 11. 13 represents one of a pair of links whose upper ends are of annular form, as at 14, to fit over the portions 7 of the bearing boxes 4, thus pivotally supporting said links at their upper ends, one at each end of the backing roll C. The lower ends of said links are solid and enlarged to add weight. In termediate of their ends'eachof said links is provided with a threaded hole 15 into which is screwed the threaded portion of the inwardly extending pivot pins 16 whose inner ends are of reduced diameter. u

D is the stripper blade,.which may be made of any suitable material, preferably hard rubber and whose top edge is beveled to .fit. snfigg against the perimeter of the backing, ro

supported by the stripper links 13. The

straps 18 may be brazed to the bracket.

19 are leaf springs one of whose ends is soldered or otherwise attached to the horizontal web of the bracket 17 and whose free ends bear against the perimeter of the roll G on the opposite side of its vertical dian1- eter from the-blade D. I prefer toprovide leaf spring adjacent to either end of the blade D and one at least intermediate thereof, so that an even resilient pressure is exerted on the blade D throughout its length.

It is evident from the foregoing that the blade D is evenly spring pressed throughout its length against the perimeter of the backing roll C and the blade is also stiffened and supported throughout its entire length by the bracket 17 to which the leaf springs are attached.

No buckling or sagging of the blade is thus possible but close contact of its entire beveled edge with the roll is insured. The weighted ends of the links 13 hold the blade and its mounting in the proper position and prevent the friction of the roll against the stripper blade or the weight of the garments passing between the backing roll and the brush from swinging the stripper blade back around the backing roll. Thus the entrance of garments, or other articles being washed, between the backing roll and the stripper blade is positively prevented and the wrapping of garments around the backing roll rendered impossible.

The suspension of the stripperblade from a point in the axis of the backing roll makes possible continued bearing of the stripper blade against the backing roll under all and any conditions of operation. Let, for instance, the clothes bunch at one end of the roll, forcing the roll away from the brush at that end and practically leaving the roll in contact with the brush at the other end, the stripper blade still remains in contact with the backing roll along its entire length, because by its method of suspension from a point in the axis of the roll, the motion of the blade must identically coincide with the motion of the backing roll.

What I desire to claim is 1. In a machine having a roll ijournaled therein, a stripper mechanism for said roll comprising a blade having its ends pivotally supported from said machine, and resilient members secured to said blade and bearing agalnst the perimeter of said roll whereby the edge of said blade is spring pressed against said roll, for the purpose described.

2. In a machine having a roll journaled therein, a stripper mechanism for said roll comprising a blade, a swinging support for said blade, and resilient members secured to said blade and bearing against the perim eter of said roll whereby. the edge of'said blade is spring pressed against said roll, for the purpose described.

3. In a machine having a roll journaled therein, a blade, a weighted swinging sup port for said blade, and resilient members secured to said bladeand bearing against the perimeter of said roll whereby the edge of said blade isspring pressed against said roll, for the purpose described.

4. 'In a machine having a roll journaled therein, a stripper mechanism for said roll comprising a blade, a swinging support for said blade in which thelatter is pivotally mounted, and resilient members secured to said blade and bearing against the perimeter of said roll whereby the edge of said'blade is spring pressed against said roll, for the purpose described.

5. In a machine having a roll journaled therein, a stripper mechanism for said roll 7 comprising a pair of' links having their upper ends pivoted to the machine adjacent to the ends of said roll, a blade having its ends pivotally supported by said links, and resilient members secured to said blade hearing against the perimeter of said roll whereby the edge of said blade is spring pressed against said roll, for the purpose described.

6. In a machine having a roll journaled therein, a stripper mechanism for said roll comprising a pair of links having their upper ends pivoted to the machine adjacent to the ends of said roll, the lower ends of said links being weighted, a blade having its ends pivotally supported by said links, and resilient members secured to said blade and bearing against the perimeter ofsaid roll whereby said blade is spring pressed against said roll, for the purpose described;

7. In combination with a machine provided with a frame and a rotary driven member mounted in said frame, a backing roll mounted in said frame in parallelism with said rotary member, means for holding said roll in resilient contact with said rotary member, means for permiting said backing roll to tilt out of parallelism with said rotary member, and a stripper blade pivot ally supported from the axis of said backing roll and held resiliently against the perimeter of. the latter, for the purpose described.

8. In combination with a machine provided with a frame and a driven rotary member mounted in said frame, a pair of links pivotally attached to said frame, a I r backing r011 having its ends journaled in stripper blade mounted on said stripper said links, spring connection between the supporting links and held in resilient con- 10 free ends of said links and said frame where tact With the perimetal surface of said by said roll is normally held in resilient conbacking roll, for the purpose described. n tact With said member, a pair of stripper Signed at Pittsburgh, Pa. this 29th day supporting links having their upper ends of November, 1915.
